词法分析gzw

说明：  这个是我编译原理课程设计的 内容，呵呵 我遍的是词法分析，基本的功能都能够实现，如词法分析，词法查错，删除无实质意义的字符等，不懂编译的就不用看了，编译真的很难！！！不过好象没什么用
(this my compiler theory of curriculum design, Oh my times of lexical analysis, the basic functions are to achieve, such as lexical analysis, lexical troubleshoot, remove no real significance of the characters, do not know the compiler would not have to read, compile it really hard! ! ! But it seems usele)
